InterCall Unified Meeting
InterCall costs $59 a month per host (or 17 cents a minute per participant), supports Windows and Mac desktop clients, but doesn’t yet have mobile client support. InterCall doesn’t have the smoothest interface or the most polish. It is best suited to small workgroups. One interesting feature is the ability to construct simple polls. You can also draw on your screen, share your Webcam and schedule meetings via an Outlook plug-in.
